IMPROVEM ENT lNwEATHER-STRIPS.

Specification forming part of Letters Patent No. 211,3] 5, dated January14, 1879', application filed i November 6, 1878. i

To all 'whom it may concern:

Be it known that I, RUSSEL I. BALDWIN, ot Shenandoah, in the county ofPage and State ot' Iowa, have invented certain new and ence being had totheaccompanying drawings and to letters of reference marked thereon,which form a part of this specification.

My invention is an improvement in weatherstrips, by which rain and windare prevented `from driving in under outside doors of dwellings, &c.

My invention consists ot' a weather-strip composed of a plate providedwith a lug or projection arranged to swing into a vertical position uponits lower edge, and a second plate fixed to the bottom of a door, Saidplates forming automatically a vertical joint by closing the dooragainst the said rst plate or its projection.

In my drawings, Figure l is a front elevation ot' the door and jamb asseen from the outside. Fig. 2' is a vertical section. Fig. 3 is a detailshowing the form of the movable plate.

Similar reference1etters indicate like parts in all of the figures.

Referring to drawings, A is a metal plate provided with a lug, a, whichrests on the sill of the door between the beveled edge of thecarpet-strip B and the rabbet-bearings of the door-frame, and when thedoor is open lies snugly against Said beveled surface, with its lug aextending above the horizontal surface ofthe carpet-sill. 4

The carpet-sillB is of the usual form, of wood, clad with metal, andprovided with a slot on the open side next to the jamb to receiye thelug a of the plate A.

C is the door, having its bottom rail provided with a metal plate, D,which is securely fastened thereto. This plate does not extend theentire width of the door, but is shortened at the open side to clear thelug a. 4

The lower corner of the door is notched and plated at g to receive andform a bearing for the lug a to bear and slide against when the door isbeing closed.

The under or bottom edge of the door is cut away to form, together withthe plate D, a U- Shaped groove, to receive the plate A when the door isclosed.

My device is simple, and can be applied to any doorway, not evenrequiring the skill of a mechanic to adjust andV put it in position.

I t is operated as follows: The door being open, the strip or plate Arests against the carpet-sill B, with its upper edge ilush with thehorizontal surface of said carpet-Sill, and the projecting lug restingin the notch provided for it. As the door is closed, the Slotbearing g,coming in contact with the lug a, forces plate A upward and outward, itentering the while the U-shaped recess or groove in the bottom of thedoor, until said plate A rests snugly against the plate D, which happenssimultaneously with the closing ot' the door against its rabbetbearings.A close joint is thus formed between door-sill and plates A and D.

I am aware of the patent to Corbit, No. 95,773, in which is a platepermanently pivoted in the doorway, said plate being thrown into placeagainst a curved plate attached to the door by the movement ofthe saiddoor as it comes against a curved arm attached to said pivoted plate,and to such I make no claim.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

'IheV weather-strip described, composed of plate A, provided with lug orprojection a, and arranged to swin g into avertical position upon itslower edge, and plate D, fixed to the door, said plates forming,automatically, a vertical joint by closing the door against the plate Aor its projection, substantially as and for the purpose set forth. r

In testimony that I claim the foregoing as my own I aflix my signatureinpresence of two witnesses.

RUSSEL r. BALDWIN.
